Hello, I'm having some trouble at setting up endless scrolling in a listview fed by a local Datasource. Here is the code that I'm using for that purpose:

// The model of the Datasource schema
var SiteModel = kendo.data.Model.define({
id: "SiteUId",
fields: {
"SiteName": {
type: "string"
},
"isDefault": {
type: "number"
}
}
});

// The Datasource
var dataSites = new kendo.data.DataSource({
batch: true,
data: userSession.sites,
schema: {
model: SiteModel
},
sort: [
{ field: "isDefault", dir: "desc" },
{ field: "SiteName", dir: "asc" }
],
pageSize: 20
});

// The ListView
var sitesList = $("#sites-picker").kendoMobileListView({
dataSource: dataSites,
template: kendo.template($("#myListTemplate").html()),
selectable: true,
loadMore: true,
click: function (e) ...
}).data("kendoMobileListView");

// The html code
<ul id="sites-picker"></ul>

I'm attaching the screenshot of the rendered view, which is not correctly showed. Thanks.

Hi Kiril,

Thanks for answering. Right now we've solved the problem mentioned before, but now the listview is having some unusual behaviour.
Sometimes a blank space is showed above the listview and sometimes the loader gets stuck and no more items of the list are shown. It usually happens at fast scrolling, when scrolling slow apparently it works well.
I've attached some screenshots of this unusual behaviour.
By the way, the version of Kendo UI that we are using is this one: Kendo UI Mobile v2013.2.1021.

Regards.

Hello Marian,

This is the answer from my colleague based on the provided sample by Christyan:

Thank you for contacting us. The issue you report is a known one, and, unfortunately, is related to the limitations of the device and the html environment. Thus being said, we are still looking for ways to avoid it - so far it is very hard to replicate and trace what exactly goes wrong (let alone address it in a reliable manner).

At this point, I can confirm that we are working on the problem – however, I can't commit that we will actually be able to resolve it.
